TO ALL WI-IOM IT MAY CONOERN:

Beit known that I, CHARLES ROBINSON, of Boston, in the county ofSuolk,-and State of Massachusetts, have invented an ImprovedChamber-Vessel; and I do hereby declare that the following is a full andexact description thereof, reference being had to the accompanyingdrawings, making part of this specification- Figure 1 `being a verticalcentral section ot' a. chamber-vessel provided ,with my improvement.

Figure 2, a top view (on a smaller scale) of the valve-cover, in whichmy invention consists.

Like letters designate corresponding parts in both figures. i

My improvemeut'consists in the employment of a hollow or concave cover,which receives the water, and conducts it into the vessel noiselessly,and is provided with a valve, that is opened in the act of sitting uponthe vessel, and again closes as the vessel is risen from.

Let A, in the drawings, represent the vessel. B is a hollow or concavecover, fitting over the rimuof the vessel, or inside thereof, ifpreferred, so as to be used in addition to the ordinary cover. Theslopeof the cover inward is such as to receive the water noiselessly, and atthe centre Or lowest part a hole, f,- ovr, preferably, holes, ff, aremade, through which the water is admitted through the cover into thevessel; and in order that no noise may be heard inside, a conical orother form of inclined or sloping conductor, g, is attached under thecover, and extends nearly down to the bottom of the vessel, so as tospread the water, and conduct it down. noiselessly. l

The apertures ff are covered by a valve, C, which is pivoted orotherwise provided-with a fulcrurn at c, with an extension, d, upward,substantially as represented. This valve is so arranged that, on sittingdown,

the extension d is depressed sufficiently to raisel the valve, and allowthe water to pass down into the'vessel.

Then, on setting the extension d free, the valve descends, and ,closesthe apertures'ff.

In order that the conductor g' may fill on a level with the rest of thevessel, and not retain water as the cover is lifted, nor tend to floatthe cover, a vent-aperture, (or apertures,) z, is made in the top, toallow the aii to pass. l

Springs or guides I b, attached tothe lower side of' the cover B, andextendingdown into the vessel, may

be used, but they are not essential.

` What I claim a's my invention, and desire to secure by Letters Patent,is

The combination of the concave or inclined cover B, and valve C, withits extension, d, arranged and operating substantially as and forthe'purpose herein specified. I f

In combination with the cover B, I also claim the -inclined conductor gbeneath, substantially as and for the purpose herein set `forth.

The above speciiication signed by me, this secondday of January, 1868.

` CHARLES ROBINSON.
